Provided is an effective amount of a desialylation agent and an effective amount of an anti CD38 antibody for use in the treatment of multiple myeloma. This results in potentiated primary NK cell activity against the multiple myeloma cell. Also envisaged is a method of treating multiple myeloma in a subject in need thereof.

Chimeric antigen receptors containing CD38 antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions, relating to the chimeric antigen receptors are also disclosed. Methods of treating or preventing cancer in a subject, and methods of making chimeric antigen receptor T cells are also disclosed.

The present disclosure relates to a bispecific reagent and a detection agent which are useful for the identification of an antibody-producing cell which produces an antibody that binds specifically to a target antigen. Further, the present disclosure relates to an assay for the identification of an antibody-producing cell which produces an antibody that binds specifically to a target antigen. The present disclosure also relates to kits comprising the bispecific reagent and the detection agent.
